Aims Increasing droughts affect crop yield and health. Plants can respond to drought by adapting their root biomass, root morphology, and quality and quantity of rhizodeposition to improve water and nutrient uptake. Besides droughts, agricultural management influences roots and rhizodeposition; however, it is not well studied how agricultural management can affect the response of roots and rhizodeposition to drought. Methods A semi-continuous 13 CO 2 isotope labelling experiment was performed in a long-term field experiment comparing biodynamic, mixed conventional, and mineral conventional cropping systems. Rainout shelters were installed to induce drought. Root, net rhizodeposition, and the rhizosphere microbiome were determined at ripening of wheat. Results Drought enhanced the total root carbon mainly through the increase of fine roots. Fine root carbon under drought was primarily enhanced in the mixed conventional and biodynamic cropping system, both receiving farmyard manure, whereas no increase was measured in the mineral fertilized conventional system. Net rhizodeposition carbon was enhanced in all cropping systems under drought, particularly in the first 0.25 m. While some plant-growth-promoting genera such as Streptomyces and Rhizophagus showed relative increases under drought, other plant growth-promoting genera often involved in nitrogen fixation such as Rhodoferax and Mesorhizobium were decreased. Conclusion This field trial suggests that drought increases total belowground carbon input via fine root and net rhizodeposition carbon inputs. Since fine root carbon increased under drought in cropping systems with farmyard manure, adding manure under future drought periods could be advantageous to increase soil carbon inputs and improve nutrient foraging.

Background and aims Soil inorganic carbon (SIC) and its dissolved fraction are recognised as dynamic components of the terrestrial carbon (C) cycle. While they contribute to CO 2 dynamics and climate regulation, their short-term responses to plant-driven processes remain poorly understood. This study investigates how growth of a C₃ species ( Silphium perfoliatum L.) and a C₄ species ( Zea mays L.) affects dissolved inorganic and organic C (DIC/DOC) dynamics in a carbonate-poor soil under varying soil moisture conditions. Methods Leachates taken from a two-week lysimeter experiment were analysed for DIC and DOC concentrations, their isotope ratios (expressed as δ 13 C isotope), pH, and the data obtained were complemented with in situ CO 2 efflux measurements. A two-endmember isotope mixing model was used to evaluate contributions of plant-derived C to the DIC pool. Results DIC concentrations exceeded DOC across all treatments. Increased CO₂ efflux and higher pH values indicated enhanced soil respiration. δ 13 C DIC values ranged from –7‰ to –20‰, while δ 13 C DOC remained nearly uniform at –29 ± 0.7‰. Isotope mixing considerations suggested that up to 62% of DIC could be derived from C₄ plant sources. Conclusion Root and rhizomicrobial respiration may measurably influence short-term DIC dynamics in carbonate-poor soils. These findings suggest that DIC fluxes could play a more prominent role in soil C cycling than currently assumed, particularly over short temporal scales.
